JotW in it's currant state was far and away OP. Spamming CS, DS, judge, consecrate and exocism, I ended fights with full mana, no pots, nothing. Let all the other mana classes do that and then we can talk.
I could walk into a 3v1 in mixed blues/epics and if divine shield was up, GG three people. Same could be said about LoH.
PuG'd gruuls in the same set of gear and in PvP spec. Ended up top damage followed by another ret. Followed by full t5 rogue/mage. No boomkins were present.
At 70, ret is completely unstoppable. If you're barely pulling off kills right now... wow you suck.
